centos下删除用yum安装的软件

作者:田逸([email]sery@163.com[/email])

yum安装软件包,方便简单.但在这个过程中,那些文件和目录都到哪里去了呢?到处都是呀!要维护这些文件,很麻烦的.前两天,我用源码安装mysql-proxy,在编译过程中,老出错,我就依提示安装mysql, 为了尽快完事,我用了yum install mysql.现在我打算重新安装mysql,因此需要把yum方式安装的mysql删除.

用rpm工具吧,不行呢.挨个删除文件,更不可行,因为我不知道究竟安装了哪些文件,都存放在哪些位置.怎么办?还好,yum自己可以完成这个工作.

现在我们来看一下yum的参数:

[root@test1 ~]# yum 

You need to give some command

usage: yum [options] < grouplist, localinstall, groupinfo, localupdate, resolvedep, erase, deplist, groupremove, makecache, upgrade, provides, shell, install, whatprovides, groupinstall, update, repolist, groupupdate, info, search, check-update, list, remove, clean, grouperase >

其中remove就是删除命令.好了,我们来执行命令 yum remove mysql ,其输出如下:

[root@test1 ~]# yum remove mysql

看,很容易就完成了.再来验证一下: 执行命令mysql,其结果为:

[root@test1 ~]# mysql

-bash: mysql: command not found

果然删除了!
